Cravings

Hey guys , So I'm 10 weeks tomorrow and this is my first pregnancy. All I've been craving is pizza and chicken quesadilla from Taco Bell. I really want to stop eating this because I know this is bad for the baby and my health ,but it is the only food that doesn't make me nasuous . Can anyone give me any ideas on healthy alternatives that are similar in which I can make instead of eating all this fast food .
